False. Granite is an intrusive igneous rock and so commonly cools slowly so has time to develop moderate to large crystals.
False. Granite is an igneous rock, formed from the cooling and solidification of magma deep within the Earth's crust. Sedimentary rocks are formed through the accumulation and consolidation of sediment particles.
I think you are talking about granitic intrusions. This is not a true/false question as granite takes many other forms than intrusions.
False. Rocks with large grains that are easily seen are described as coarse-grained, not fine-grained. Fine-grained rocks have smaller grains that are not easily visible to the naked eye.
True. The color of granite is determined by the presence and ratio of minerals such as feldspar, mica, and quartz. Pink granite typically contains more feldspar, while black granite contains more mica and quartz.
True. Intrusive igneous rock, also known as plutonic rock, forms larger crystals because it cools slowly underground. Extrusive igneous rocks cool rapidly on the Earth's surface, forming smaller crystals.
False. Granite is an igneous rock, formed from the cooling and solidification of magma deep within the Earth's crust. Sedimentary rocks are formed through the accumulation and consolidation of sediment particles.
It is false. Granite is a igneous rock that was formed from magma cooling and hardening.
Yes, the continental crust is primarily composed of rocks such as granite, which is a common type of intrusive igneous rock. Granite is a light-colored, coarse-grained rock that is abundant in continental crust and is formed through the cooling and solidification of magma beneath the Earth's surface.
Felsic igneous rocks (the lightest in color) are comprised mostly of quartz and potassium feldspar. Intermediate igneous rocks (somewhat darker than felsic) are made up of some quartz and potassium feldspar, but mostly plagioclase feldspar.
I think you are talking about granitic intrusions. This is not a true/false question as granite takes many other forms than intrusions.
False. Rocks with large grains that are easily seen are described as coarse-grained, not fine-grained. Fine-grained rocks have smaller grains that are not easily visible to the naked eye.
Yes, the size of igneous rock crystals is influenced by the cooling rate of magma or lava. When magma cools slowly beneath the Earth's surface, it forms larger crystals, resulting in coarse-grained rocks like granite. Conversely, when lava cools rapidly on the surface, it forms smaller crystals, leading to fine-grained rocks like basalt. Thus, the cooling rate directly affects the texture and crystal size of the resulting igneous rock.
True. The color of granite is determined by the presence and ratio of minerals such as feldspar, mica, and quartz. Pink granite typically contains more feldspar, while black granite contains more mica and quartz.
False Sedimetary rocks can be formed from changes in igneous rock, and igneous rock can be from changes in sedimentary rock.
That is false. The 3 main types of rocks are igneous, sedimentary, and metamorphic
True. Intrusive igneous rock, also known as plutonic rock, forms larger crystals because it cools slowly underground. Extrusive igneous rocks cool rapidly on the Earth's surface, forming smaller crystals.
False. Igneous rocks are primarily classified by their origin (intrusive or extrusive) and their mineral composition, rather than their texture or shape. Texture can be a characteristic used to further describe igneous rocks, but it is not a primary method of classification.
